To all whom it may concern.

' Be-i't known that I, EDWARD E. GOLD, -a

citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Valves for Heating Systems and the like, of which the following is aspecification.

invention has reference to a valve adapted particularly for use in a heating system and provides means whereby the amount of radiating pipe filled with heating fluid maybe controlled so that more or less of the said radiator may be heated according to the weather..

i Mydnve'ntion is particularly adapted for use ina'steam heating system and is illustrated-f-a's applied to a steam heating system for in railway passenger cars for which it is well-adapted. I do not concede, however','that'my valve for admitting fluid to one or more radiator pipes is necessarily limited to a steam heating system, nor to a system for heating railway cars, as it may be used upon other systems supplying fluid heating media and in other uses than upon A desired 'form in which my invention may be embodied is; illustrated in the accompanying drawings, wherein,}

Figure 1 illustrates a plan view. of a portion of a'car equipped with my invention; Fig. 2 is a cross section on the line 22, Fig. 1; Fig. 3 is a section of the said valve on the line 33, Fig. 4, illustrating the valve in .closed position; Fig. 4 is a plan view partly in sect1on of Fig. 3; Fig. 5 is a view looking from the left side of Fig.3 partly in section illustrating the device with heating fluid being admitted to one radiator; Fig. 6 is a section on the line 6-6, Fig. 5; and Fig. 7 is a section somewhat similar to Fig. 6 partly broken away to illustrate the outlet ports and showing an adjustment wherein both ports are opened.

In the particular illustrated my invention I have shown the valve as applied to a steam heating "system for use upon a railway car. Here steam is taken from the train pipe A through a branch B which extends through the double floor C of the car and leads tothe valve D.

The .inlet pipe B is attached to this valve Specification '0! Letters Patent.

form in which I have so as to admit steam thereto. Leading from the valve are radiator pipes E, F which lead to the respective longitudinal radiating pipes G, H and these pipes have respective returns 1, J which are connected to a common outlet K and exhaust throu h a connnon drip L which may be 0 any usual construction. Preferably an inlet valve M will be located in the inlet pipe B and will be subject to the control of the thermostatic means located in the outlet L, butthe construction of the said inlet valve M and outlet pipes. K, L forms no part of the present invention.

My invention is concerned with the provision of means whereby the heat is admitted to a greater or less extent of radiator surface as required, and such means are provided in the valve D, which is illustrated on Sheet 2 of the drawings, ,wherein Figs. 3 and 4: the valve is shown adjusted to shut steam off from both of the radiators; Figs. 5 and 6 is an adjustment which admits steam to one of the radiators, and Fig. 7 in an adjustment which admits steam to all of the radiators. -.The valve has a rotary disk N which is provided with a suitable wearing face 0 formed of any material usually employed for thispurpose, such as the material known as bakelite. This is retained in a seat formed within a flange n of the disk N and is held in position against turning by suitable means, such, for instance, as a dowel 0 upon the face 0 which is received in a corresponding recess 10 in the disk N. The disk N is turned by a valve stem P having a handle 2. This valve stem enters a recess n in the disk N andis so connected thereto that the said disk may be turned by the said stem and at' the same time per- Patented Mar. 30, 1915.

mit the disk to have a slight longitudinal movement relative to the stem. To aid in the turning of the said valve the stem has ribs 30 which are received in a slotted annular sleeve n. extending upwardly from the a valve stem as usual. An indicator S has a depending toes which. indicates upon a.

track T formed in the casing U and having recesses t t t The indicator S has a slight spring-2 movement which causes the too -8 to pass into the recesses t t t and hold the disk N in adjusted position. In the construction shown when the' toe ..'s is in the position 25 the valve-is closed, when it.is in t theuvalve is admitting steam to one of the radiators, and when it is in t it is admitting-steam to both of the radiators. The indicator S is adjustably attached to the handle 7) as by nuts t.

The casing U is provided with a flange V inclosing theinlet port and-which is adapted to receive the steam inlet pipe B. It is also provided with sockets W, W which form the outlet ports and are adapted to receive the radiator pipes E, F.

. The disk N is'provided with ports Y Y seen in dotted lines in Fig. 4 and these ports are preferably the same size and are located the same distance apart as the outlet ports -X,.X In the instance shown there are but two radiators E, F and therefore the outlet ports are twoin numbenand these ports in the casing are arranged in quadrature with the corresponding ports in the valve disk.

In the use of my invention as applied to the particular system illustrated steam being admitted through the train pipe A will pass through the supply pipe B to the valve D. If this is turned off, that is if the indicator S is in the position It, steam will not be admitted. If the indicator should be intheposition t the ports Y Y will have made a quarter turn so as to cause port Y tobealined with the outletport X (Fig. 5)

and steam will therefore flow through said portto the connected radiator E G... If the indicator S should bein the position t the two portsY Y will each have made a half turn and will be in alinement with the outlet ports X X as indicated in Fig. 7, whereupon steam wil-l. flow to both of the radiators. I

I have indicated in the accompanying drawings two radiators situated upon one side of a car. The number of radiators is not material. There may be more than two, in which case the valve ports Y Y .ma be correspondingly increased and there wi l he. an outlet portlX' X for each' radiator. It will be observed that the valve orts Y Y are of the same size and situate the same distance apart-as are the outlet ports presses the valve N down, thereby causing both parts to fit tightly against their respecvalve climber reinforces this double action of the spring by pressing the collar'p up- Wardly against its seat, and by pressing the valve N downwardly against its seat: This causes the. collarp fltoipress-againstits seat with such force that it becomes practically self-- sealing.- Th ereupon the stufling box R might be omitted, and if this stuifing box is usedit-may be packed without shutting ofi steam as the gland-r may be unscrewed and the box repacked', and during this operation the disk p prevents escapeof steam.

. In the foregoing embodiment of my invention it will be observed that port- X is first opened. Therefore when steam is desired inbut one radiator it is admitted to radiator EG which is nearest the side of the car. The passengers are then protected by the cold radiator H against burning themselves. It will alsobe observed that I have described and illustrated radiators upon but .one sideof a car. The arrangement on the other side of the car as illustratedis a duplicate of that above described, having its-own admission valve and its own return pipes.

The apparatus and devices herein described are illustrative of-one embodiment of the invention and are not to be understood as lim iting me to the particular construction or constructions illustrated. For instance outlet ports may be provided in number, as desired for attachment to any desired number of radiator pipes and the valve and seat will have a corresponding number of ports. .Any desired number of radiators may be employed. Likewise the valve construction may be modified and the valve although illustrated with a plurality-of outlet ports may be employed withadvantage ina construction where only one radiator is present, and in this case but one outlet p'ortwouldbe necessary. These and other modifications within the limits of the appended claims are con templated by me, and are within my invention. i

What is claimed is: p
